Carbon Fiber Sheets, known for their high strength and lightweight properties, are widely used in various fields. Special material machining, especially special material CNC machined parts, plays a crucial role here. Through special material CNC processing and precise special material processing techniques, these sheets can be crafted into complex components. This machining method ensures high precision and stability, meeting the strict requirements of industries like aerospace and automotive, where quality and performance of special material parts are paramount.
Processing Technology of Carbon Fiber Sheets:
1.First is cutting, which involves cutting the entire carbon fiber sheet into the required shape and size. Common methods include laser cutting, which is similar to using a laser pointer to draw lines on paper but with much higher power, resulting in fast and neat cuts; there is also water jet cutting, where high-pressure water mixed with carborundum is used to cut through even the hardest sheets, making it suitable for materials sensitive to high temperatures.
2.Next is polishing. The surface of a newly made carbon fiber sheet may be a bit rough, so it needs to be polished with sandpaper or a grinder to make the surface smooth. Sometimes, this is also done to ensure better adhesion between the sheet and other components.
3.Then comes drilling, which is like making holes in wood. Special drills are used to create screw holes or mounting holes in the sheet. However, carbon fiber is relatively hard, so the right drill must be selected; otherwise, it is easy to crack the sheet.
4.There is also forming, a process used during the production of the sheets. For example, hand lay-up forming, where workers lay carbon fiber cloth layer by layer on a mold, apply glue, and let it dry to form the sheet, which is suitable for small-batch production; there is also compression molding, where materials are put into a mold, heated and pressed to form the shape like making cookies, which is efficient and suitable for mass production.
5.In addition, there is splicing. Sometimes, a single sheet is not large enough, so several sheets are glued together or fixed with screws. However, the joints must be properly handled during gluing; otherwise, the structure will not be strong.
6.There is also CNC machining, which is similar to numerically controlled lathe processing of metals. Computers control the machine to mill complex shapes, such as grooves and steps, on carbon fiber sheets. It has extremely high precision and is suitable for making parts with fine structures.
